To all whom'a't may concern:

, Be it known that I, Smnon C.'LAWL0R, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and 'useful Improvements in Mopping Appliances;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7 I An object in view is the provision of mop wringing means constructed to effectively ip a mop and prevent slipping thereof. With this and further objects in view, as will in part hereinafter become apparent and in part be stated, the invention comprises certain novel constructions, combinations and arrangements of parts as will be subsequently specified and claimed.

In the accompanying drawing,'- v Figure 1 is a detail, fragmentary view, partly in elevation and partly in section, of

' a roller embodying the features of the present invention.

Fig. 2 is a transverse section taken-therethrough on the plane indicated by l1ne 2-2 of Fig. 1.

Fig. 3 is a modified form of roller adapted to cooperate with the roller seen in Fig. 1.

Fig. 4 is a transverse section taken on the plane indicated by line 44 of Fig. 3.

The invention relates to that class of mop wringers in which one'roller is journaled in a stationary support and a cooperating roller is journaled in a movable support so as to be shifted toward and away from'the first roller. 1

The stationary roller is seen at 23 in the accompanying drawing and consists of a tubular cylinder formed of sheet metal, the edges of the metal abutting and stifi'ened by similar sheet metal rings 24, 24 arranged within the roller 23 with the abutting ends of each roller arranged diametrically opposite the abutting edges of the roller, as clearly seen in Fig. 4. The ends of the roller 23 are formed with stiffened caps 25 and a centrally arran ed shaft 26 extends through the roller an cap and is adapted to have its ends appropnately ourualed 1n Specification of Letters Patent.

and connecting them by an interlocking splice 44. To cause the roller 39 to firmly grip an engaged mop and-to prevent slipping of the roller during wringing of the mop, the roller is formed-with apertures 45, 45, with indentations 46, and with projections 47. The said apertures, indentations and projections may be arranged in rows or may be merely miscellaneously distributed. Shaft 42 extends centrally throughout roller 39 and is fixed thereto by extending-through the end caps 25' thereof, similar to cap 25, and having through pins or rivets 26 extending through the flanges of said caps and through the shaft 42. An operating crank or other appropriate means (not shown) for rotating roller 39 is preferably connected to the shaft 42.

The operation is the same as that of any of the known form of mop wringers, such as, for example, is seen in my Patent No.

1,082,465, dated December 23, 1913, except that the roller 39 is particularly constructed to grip the mop and prevent slippage thereof in its passage between the rollers.

I claim v 1. In a wringer roll, the combination of a longitudinally spaced apart reinforcing means, a cap fitting in the end. of the body and being centrally apertured to receive a shaft, the cap having inner and outer marginal flanges extending in the same direction and adapted to engage the shaft and the body, and a cross pin adapted for engagement through the body and through the flanges of the cap 7 for retaining the latter in the body and holding the roll from sliding on the shaft.

2. In. a. wringer roll, the combination of a g; werewfor sunportmg the same. M, DAVIS.
